T0 all whom it 'may concern,.-

Be it known that we, VILLIAM B. REILLY and SAMUEL D. `WnBB, citizens of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Smoking-Pipes, of which the following is a specification.

This invention relates to smoking-pipes.

The objects of the invention are in a ready, simple, thoroughly feasible, and practical manner to facilitate cleansing of the pipe, to preclude entrance of tobacco to the stem, thereby obviating all danger of fouling or clogging, to catch and retain. nicotin in such manner as positively to prevent its escape to the bowl, thereby causing the latter to remain clean and sweet and pleasant in use, and, further, to present a pipe combining all of the above advantages which shall be siniple of construction and no more expensive to produce than pipes generally employed.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists7 generally stated, first in a novel form of drafttube for smoking-pipes embodying a plurality of sections and assembling means constituting a closure for one end thereof.

The invention consists, secondly, in a drafttube for pipes embodying a plurality of sections, assembling means therefor constituting a closure for one end, and an absorbent for moisture combined with the tube.

The invention consists, thirdly, in. a drafttube for pipes including a plurality of sections, means for holding the sections assembled and constituting a closure for one end thereof, and means for holding the tube assembled with the mouthpiece of the pipe.

The invention consists, further, in the various novel details of construction and arrangement of parts of a smoking-pipe, as will be hereinafter fully described and claimed..

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there are illustrated seven forms of embodiment of the invention, each capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in vertical longitudinal section through a pipe, showing one form of draft-tube combined. therewith. Fig. 2 is a perspective detail view of the draft-tube removed from the pipe. Fig. 3 is a detail view in plan of the two sections of the draft-tube separated. Fig. 4 is a perspective detailviewof a slightlymodified forni oi. draft-tube wherein the threads for engaging the mouthpiece are dispensed with. Fig. 5 is a view in elevation of another form of draft-tube in which. a slightlymodified form of assembling means is employed. Fig. 6 is a perspective view of still another form of draft-tube, showing a hinge for holding the sections of the draft-tube assembled.. Fig. 7 is a sectional detail view of the draft-tube, showing the same provided with a lining of absorbent material for catching and retaining the nicotin. Fig. 8 is another form of draft-tube wherein the sections thereof provided with lugs for enoraging notches in the stem of the pipe to hocld the tube against turning, so that the draft-openings will always be in proper position with relation to the bowl. Fig. 9 is a view of a slightly-modified forni of draft-tube. Fig. l() is a view of a still further modified form of draft-tube.

Referring to the drawings, A designates a pipe, which in this instance is shown as provided with a` straight stem B and a straight mouthpiece O. It will be understood, however, that the invention is adapted to pipes having slightly-curved stems and mouthpieces, and as this will be obvious detailed illustration. thereof is deemed unnecessary.

The essential feature of the present invention resides in a novel form of draft-tube l, (shown in detail and in various forms in Figs. 2 to 9,) this tube being made of any material suited to the purpose, such as metal or a composition of matter capable of withstanding the heat to which it will be subjected in use. In each of the forms of embodiment of the invention illustrated the tube is shown as constructed of two sections; but it is to be understood that the invention is not to be limited to this number, as three ormore sections could be employed and still be within.

the scope of the invention; but for practical purposes it has been found that two sections are best adapted for use. Each of these sections 2 and 3 is a counterpart of the other, except that the section 2 is provided with a plurality of draft-openings 4, which when the tube is positioned within the pipe are disposed in the bottom of the bowl, as clearly shown in Fig. l.

In order to keep the sections of the tube assembled, thus to present a structure that will catch and retain nicotin, a locking or assembling device is employed, and this device also subserves the further function of preventing the escape of nicotin from the tube to the bowl, whereby the latter is kept sweet and clean in use and its usefulness is greatly en hanced.

The form of combined assembling device and closure shown in Figs. 1 to 3 consists of two lugs 5 and 6, the lug 5, which in this instance is carried by the section 3, being disposed on the end of the section and the lug 6 a distance back of the end of the section 2 lequal to the thickness of the lug 5, so that when the two lugs are interlocked the closed end of the tube will present a straight wall.

V The stem B is bored out to receive the tube,

and the bore is extended a distance beyond the bowl, as shown at 7, to house the closed end of the tube. The draft-openings 4, of which there may be any preferred number, three being shown in this instance, are of such size that while permitting free draft through the tobacco, and thus passage of smoke to the stem, will positively preclude the entrance of tobacco to the tube, so that the latter will always remain free; but in the event that any dust present in the tobacco or finely-powdered tobacco should find en trance to the tube it may be readily removed by detaching the draft-tube from the stem and separating the parts, as shown in Fig. 3. As a means for assembling the tube with the mouthpiece the former is provided at the end opposite the draft-openings 4 with threads 8, which engage internal threads 9 in the mouthpiece. It will generally be preferred to employ the threads 8 and 9 for the purpose defined; but, if preferred, the threads 8 may be omitted from the tube, as shown in Fig. 4, and the tube may be held within the mouthpiece by frictional engagement with the bore thereof.

In the form of embodiment of the invention shown in Fig. 5 the lugs 5 and 6 are dispensed with and the assembling device and closure 10 is in the form of a cap of the same external diameter as the tube and which is slipped over the end thereof, the tube being slightly reduced in diameter at this point, so that when the cap is positioned thereon the tube will be of the same diameter throughout its length. By this arrangement when the tube is removed from the stem the cap will not be detached. The cap in this instance is held in position by frictional contact with the tube; but, if preferred, a thread connection may be provided for holding the parts assembled, and as this will be understood illustration is deemed unnecessary.

In the form of embodiment of the invention shown in Fig. 6 the assembling device and closure is in the form of a hinge 1 1, which may be of the usual or any preferred con struction. In some instances it may be advantageous to combine an absorbent for nicotin with the tube, and this form of embodiment of the invention is shown in Fig. 7, wherein the Ymoisture absorbent 12 may be either fabric, meerschaum, or any other material or substance suitable for the purpose.

In the form of embodiment of the invention shown in Fig. 8 each section of the tube is provided with a lug 13, said lugs being de signed to engage with recesses 14, formed in the stem of the pipe, thus to hold the tube against turning, so that the draft-openings 4 will always be in proper relation to the bowl.

In the form of embodiment of the inven tion shown in Fig. 9 there is combined with each section of the tube an internal half-collar or stop 15, disposed near the threaded end thereof, the object of which is to check any tendency on the part of the nicotin to enter the mouthpiece.

In the form of embodiment of the invention shown in Fig. 10 another construction of removable assembling and closing device is employed. In carrying this form of invention into effect each section of the tube is provided at one end with a longitudinallydisposed groove or depression 16, which is adapted to be engaged by spring locking members carried by a disk or plate 17, provided with a centrally-disposed boss 18 to engage the bore of the tube, the spring locking members 19 being of such diameter that when seated in recesses tney7 will lie flush with the exterior of the tube, and thus present no obstructions to the removal of the tube from the stem.

In each form of the embodiment of the invention itwill be noted that the tube is of the same diameter throughout its length-that is to say, the assemblage and locking means in each instance is contained within the diameter of the tube, so that the closed end of the tube may always be housed within the bowl, if so desired.

It may be stated at this point that by the provision of the seat 7 in the wall of the bowl to receive the closed end of the tube escape of nicotin to the stem or bottom of the bowl is still further prevented, and in addition to this this seat causes the tube closely to bind against the bore of the stem, and thus prevents the nicotin from escaping around the tube to the stem.

All of the forms of embodiment of the invention shown are adapted to perform the functions designed., and owing to their simplicity of construction and readiness with which they may be manufactured their addition to an ordinary pipe will not increase its' cost to any appreciable extent.

It will be seen from the foregoing description that each of the objects set forth is secured in a ready and practical marmer and that without labor or objectionable soiling of the hands the pipe may be cleansed of any accumulated nicotin simplybyremoving the mouthpiece, detaching the draft-tube, separating the sections, and cleansing them.

Having thus described the invention, what we claim is* l.. As a new article of manufacture, a draft-tube for smoking-pipes enibodying a plurality of sections, means, constituting,r a closure for one end thereof, for holding the sections assembled, and an absorbent for moisture combined with the tube.

2. As a new article of manufacture, a draft-tube for smoking-pipes embodyingr a plurality of sections, one end of each section being provided with threads and the opposite end of one section with draft-openings, and means within the tube-sections constituting a closure for one end of the tube for holding the sections assembled.

3. As a new article of manufacture, a draft-tube for smoking-pipes comprising a plurality of semicylindrical sections each of which is provided at one end with threads, one of the sections being provided with draftopenings and with a lug adjacent thereto and the other section with a lug to interlock with the Afirst-named lug to present a closure for one end of the tube.

Ll. As a new article of manufacture, a draft-tube for smoking-pipes having one end sealed by a closure contained within the diameter of the tube, and draft-openings disposed adjacent tothe said end, and its opposite end threaded.

5. The combination with a pipe having' a stem provided with a bore extending into the wall of the bowl, of a multipart draft-tube having one end closed and provided with draft-openings, said closed end fitting into the bore of the bowl, the free end of the tube being threaded, and a mouthpiece having internal threads to engage the threads of the tube and external threads to engage the threaded portion of the stem.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
